Influence of hydroxyis, carbonates and chiorides ions on the pitting corrosión of steel in concrete
The electrochemical process of steel corrosion in concrete are studied by simulating its liquid phase with synthetical solutions in a large range of hydroxyls, carbonates and chlorides ions.The steel specimen is either under or without an electrical polarization. The present analysis has made it possible to define a new relevant parameter, which is the [CΓ]/[AIK] ratio (where AIK is the total alkalinity). It characterizes the conditions of the polarized steel pitting corrosion. Furthermore, the investigation showed out that a polarization at potentials lower than — 700 mVSCE, stops the corrosion processes.
